Answer:
Explanation:
The statistic shows the fastest roller coasters in the world in 2021, by top speed
Answer:
all of them can be uncontrolled but the one who is not controlled would be the effect of heat on a plant growth
Explanation:
We know from the question that the Mass of the elastic object m = 0.00040 kg
Its Spring Constant is given as k = 40.0 N/m
Velocity required when the object is launched V = 16.0 m/s
Distance the elastic object has to be stretched from the equilibrium x = ?
We can use Conservation of Energy in this case, which tells us that
Elastic Potential Energy stored in the elastic object = Kinetic energy gained by it when released
We see that the 1/2 cancels from both sides and we are left with
Making x the subject of the formula, we have
Plugging in the numbers and solving for x, we get
Therefore, x = 0.05 m
The object has to be stretched by 0.05 m from its equilibrium position.
Answer:
b.
Explanation:
a. from the spring-mass system which is explicitly describe by hooks law
from
F=-kx
which is in comparison to newtons general law of motion
F=ma
where the displacement x is expressed as
and the acceleration is the second derivative of the displacement
hence final expression after substituting for the acceleration and the displacement is expressed as
b. for k=105N/m and m=3.4kg
we have the angular frequency to be
The force is 1.5N acting downward or -1.5N.
Why?
To answer this question, we need to remember the Newton's Third Law. This Law states that for every force applied upon an object, there is an equal force acting in the opposite direction. This Law is also called "action-reaction Law".
So, if the force of the players heads applied on the ball is equal to 1.5N (upward), the force applied by the force on the players heads will be exactly equal, but with opposite direction, or -1.5N (downward).
Have a nice day!
